Step 9

Running the wire

If your run is uncomplicated, just tape your black, white and ground wires together and push them through the pipe. Make a loop in one end of one wire to make it easier to maneuver through couplings and bends. For longer runs or several bends, use a fish tape. Leave eight inches or more of excess length at each box so you can wire your receptacles.

Garage and basement receptacles must be GFCI protected, and this can be accomplished by a GFCI breaker or a GFCI receptacle that protects the rest of the circuit.

If you already have a GFCI breaker or receptacle protecting the circuit, you can use regular 15-amp, tamper-resistant receptacles for this project. If not, break off the ears of your GFCI receptacle so it will fit in the first box and screw into the industrial cover.

Follow the wiring instructions on your devices — the power supply goes around the “line” terminal screws (don’t use the push-ins), and the downstream wires go on the load side (remove the yellow tape).

Connect the ground screw on the receptacle, the ground screw on the electrical box (use a pigtail) and the green equipment grounding conductor together at each box.

As always, consult a licensed electrician if you need help.

FAQs

Is surface wiring legal?

Yes, but not all locations have the same rules for damage protection, or allowable wiring methods and raceways. Consult a licensed electrician for specifics if your installation varies from this one.

Is surface wiring cheaper?

It can be. Conduit, boxes, fittings and your labor cost money, but the alternative (opening up the wall) has its own cost considerations.

How much does it cost to wire a 2,000-sq.-ft. house?

It depends. Material and labor costs vary widely across the country, as do aesthetic or optional choices by homeowners. According to HomeGuide’s tracking of millions of contractor estimates, the average is $6 to $9 per square foot, or $8,000 to $18,000 for a 2,000-sq.-ft. house.
